802.11bWireless Internet around the house is great. In the last year, we've upgraded the house from 56K to wireless broadband. The office DSL is almost as good. It's great to grab the laptop and head downstairs for an early-morning cup of coffee.
The important thing isn't speed. It's ubiquity, the sense that the Net is wherever you want it to be. Not dialing a modem makes a big psychological difference; instead of the Net being a separate activity, it's just there.
